Am planning buying Pro. Will be switching from Air 14'. air started showing some tear in display quality in performance (the fun started working this past couple of weeks while connected to my external display 27') especially after I played around with my friends 15' pro I mean the RETINA is awesome on macbook. Now, heres question. Should I wait until the new one or just upgrade on this upcoming holidays? Do you think I will really miss out on the next model ("if" rumored for beginning of next year) if I upgrade to the 15' version? Or I should just wait and see the new model and use the price drop after the new one announced and get the 15' model if improvements are minor. I am not really in a rush. Will be using this Pro for mostly college work and the website I've been working on.
